Abstract
An experiment was conducted for plant selection to determine genotypes tolerant to chilling injury from lines of a genetically diverse population commenced in the greenhouse. Seventy nine sweetpotato F1 breeding lines from three major variety crosses including ‘Vardaman’, ‘Jewel’ and ’MD-708’ were selected for tolerant to chilling injury. Information on the response of these lines to chilling prior to this study did not exist. Selection procedure was developed to identify chilling tolerant sweetpotato genotypes. Following chilling exposure, qualitative visual ratings of the tolerant genotypes were different but the lowest score of the four on the scale of five was still considered chilling tolerant.
